Further, a seal member 55 is fitted on the inner periphery of the mounting cylinder portion 51. The seal member 55 has a flange-like seal lateral wall portion 57 extending inward from the lower end of the outer peripheral wall 56 fitted to the inner peripheral upper end portion of the mounting cylinder portion 51, and seals upward from the inner periphery of the seal lateral wall portion 57. A cylindrical wall portion 58 is extended. Further, the upper end of the narrow tube 60 having the lower end fitted liquid-tightly to the inner circumference of the seal cylinder wall part 58 is fitted to the reduced diameter part 53a of the neck 53 and protrudes upward.

  A nozzle 70 is fitted on the upper end of the base cylinder member 50. The nozzle 70 is provided with a base member 72 bent from the lower surface of a fitting cylinder 71 fitted on the outer periphery of the reduced diameter portion 53a and bent into a dogleg shape. And an inclined hole 74 that communicates with the base end at the upper end of the vertical hole 73 and opens the other end obliquely upward. Further, a discharge hole member 75 is fitted at the tip of the inclined hole 74. The discharge hole member 75 has a discharge hole 77 opened at the tip of a discharge cylinder 76 whose base end is liquid-tightly fitted to the tip of the inclined hole 74, and a support cylinder 79 is extended to the outer peripheral edge of a flange 78 extending from the outer periphery. Has been established. A flexible cylinder 80 protrudes in the form of a taper cylinder from the tip of an engagement cylinder 81 fitted to the outer periphery of the support cylinder 79, and the flexible cylinder 80 has a brush or sponge indicated by a dotted line on its inner periphery. Etc. are supported. A flow path is provided in which one end is opened to the storage chamber 17 and passes through the narrow tube 60 and the other end is opened to the discharge hole 77. In the figure, 90 indicates a cap.

  The case where the application container 1 configured as described above is used will be described. When the cap is removed from the state of FIG. 1 and the rotating body 23 is rotated in a predetermined direction with respect to the lower peripheral wall portion 20, the cylindrical portion 29 rotates in the same manner. The lifting cylinder 31 is rotated by the engagement. The rotation of the elevating cylinder 31 causes the elevating cylinder 31 to be lifted by screwing the thread 33 on the outer periphery of the elevating cylinder 31 with the thread piece of the screw plate 22, and at this time, the engaging protrusion 32 is formed in the concave groove 28. Ascend along. Along with this, the movable bottom wall 14 rises, and the liquid in the storage chamber 17 is discharged from the discharge hole 77 through the flow path.

As shown in FIG. 3, when the movable bottom wall 14 rises to the highest position and the liquid in the storage chamber 17 is exhausted, the refill container 100 can be used again by exchanging a part thereof. As shown in FIG. 6, the refill container 100 includes an upper component A ₁ having a movable bottom wall 14 built therein, and an upper lid 101 and a lower lid 102 are vertically mounted on the upper component A ₁ . As shown in FIG. 3, after the spout B is removed from the application container 1 that has finished using the stored liquid, the upper component A ₁ is unscrewed from the lower component A ₂ . Next, when the lower component A ₂ pushes down the lifting cylinder 31 from the state of FIG. 4, the lifting cylinder 31 is lowered to the original state as shown in FIG. The lowering and lowering cylinder 31 is lowered by rotating the rotating body 23 in the opposite direction with respect to the lower peripheral wall portion 20. In this case, a thread piece on the lower peripheral wall portion 20 side is formed on the screw plate 22. Since it is intermittent, it can be forced down, and the original screwed state can be maintained after the push down.

Then, for example, after disconnecting the upper lid 101, and screwing the spout B, then a new coating container 1 by screwing the lower structure portion A ₂ in the state of FIG. 5 after removal of the lower cover body 102 be able to.

  FIG. 7 shows another example, and in the example of FIG. 1, an example in which the elevating cylinder 31 and the movable bottom wall 14 are connected via the first connecting member 105 and the second connecting member 110 is shown. In this case, the elevating cylinder 31 has an upper end portion formed in the large diameter portion 31a, and a first connecting member 105 is fitted to the inner periphery of the large diameter portion 31a. The first connecting member 105 has a taper-shaped taper projection 107 protruding downward from the inner periphery of the fitting tube 106 fitted to the inner periphery of the large-diameter portion 31a, and the second connecting member. 110 is formed of a flexible and elastic material such as an elastomer, and a fitting tube portion 111 fitted to the inner periphery of the connecting tube 18 is raised from the upper surface of the top plate 112, and an annular locking is provided from the lower surface of the top plate 112 to the outer periphery. A columnar part 114 projecting from the projecting part 113 is suspended. The peripheral edge of the top plate 112 is in contact with the large diameter portion 31a and the upper surface of the fitting cylinder 106, and the tip of the taper protrusion 107 is in pressure contact with the upper surface of the locking protrusion 113. The other configuration is the same as that of the example of FIG.

  In this case, the second connecting member 110 can be connected to correct the dimensional error.
